A catheter comprising the coating on the expandable portion and a method for treating a condition are also provided.

The invention relates to a surgical or wound dressing comprising a sheet of gellan gum and an antifibrotic agent. Methods of producing dressings comprising gellan gums and biologically active agents area also produced.

Embodiments of the invention include drug delivery coatings and devices including the same. In an embodiment, the invention includes a drug delivery coating including a polymeric layer. The polymeric layer can include a hydrophilic outer surface. The coating can also include a matrix contacting the hydrophilic outer surface. The matrix can include a particulate hydrophobic therapeutic agent and a cationic agent. The polymeric layer can further include a hydrophilic polymer having pendent photoreactive groups and a photo-crosslinker including two aryl ketone functionalities. Other embodiments are also included herein.

Disclosed are nucleic acid-calcium phosphate nanoparticle complexes and application thereof in biomineralization. Specifically, disclosed are a biological mineralizer and a preparation method thereof. The mineralizer contains a complex formed by nucleic acid and amorphous calcium phosphate nanoparticles. Further, disclosed is a collagen fiber product containing the biological mineralizer or treated with the biological mineralizer, such as a medical device for being implanted into a patient. Further, disclosed is use of the biological mineralizer or the collagen fiber product in treatment of bone-associated diseases or disorders or improvement of bone conditions of patients. Further, disclosed is a method of using the biological mineralizer to induce biomimetic mineralization of collagen fibers or a preparation method of a mineralized collagen fiber product.

The invention provides a novel, versatile degradable hydrogel composition, and methods thereof, with precisely tunable stiffness, plasticity (e.g., degree of covalent vs. physical crosslinks) and predictive disintegration rates degradation, allowing controlled disintegration and release of therapeutic cells or pharmaceuticals and/or in vitro 3D cell expansion.

The present application is directed to a method of treating osteoarthritis, which includes obtaining a member of a transforming growth factor superfamily of proteins; obtaining a population of cultured mammalian cells that may contain vector encoding a gene, or a population of cultured connective tissue cells that do not contain any vector encoding a gene; and then transferring the protein and the connective tissue cells into an arthritic joint space of a mammalian host, such that the activity of the combination within the joint space results in regenerating connective tissue.

Disclosed herein are embodiments of a polymer-based implant and methods of making and using the same. The polymer-based implant comprises a polymer component and a therapeutic agent. In some embodiments, the polymer-based implant can be used to treat and/or prevent retinal diseases and/or retinopathies. The polymer-based implant exhibits physical properties that provide the ability to safely place the polymer-based implant in an ocular region without undesired diffusion and also to allow for controlled and timely release of the therapeutic agent to a desired region of the ocular region, such as the retina. In particular disclosed embodiments, the polymer-based implant can be used for safe and effective gene therapy.

A coating for an expandable portion of a catheter comprising a lipophilic matrix and a plurality of micro-reservoirs dispersed in the lipophilic matrix is disclosed. The plurality of micro-reservoirs comprises an active agent. A coating formulation and a method for forming the coating are also disclosed. A catheter comprising the coating on the expandable portion and a method for treating a condition are also provided.

The present disclosure relates to the field of medicines, in particular to the use of IGSF10 in the preparation of a bone tissue regeneration product, especially the use of IGSF10 in combination with BMP in the preparation of a product for promoting bone tissue regeneration. The product includes a periodontal bone defect repair product, a jaw bone defect repair product and/or a skull defect repair product. The new use of IGSF10 of the present disclosure can reduce the effective concentration of BMP without obvious adverse reactions, thereby exploring a method to promote bone tissue regeneration and providing new ideas for the treatment of bone defects.

Methods of treating, reducing the risk of, preventing, or alleviating a symptom of inflammation or inflammatory disease, including wounds, diabetic ulcer, and inflammatory bowel disease, by administration of gel-based delivery particles, such as zwitterionic copolymer cryogels or chitosan microgels, containing cerium oxide nanoparticles.
